The only thing that bothers me about this book is that there was too much revelation about Anakin to Leia. Then at the end Luke was just "Oh, yeah, I knew all of that, but I was just keeping it all secret". I think with this much revelation all at once, it sort of affects perceptions in previous novels that take place chronologically after this story. They should have saved some of it for later and just delved deaper into some of it.
